Brand: EDWARDS

Model: 126 GuardSwitch

Type: Installation guide

EDWARDS 126 GuardSwitch is a magnetic door position switch that provides reliable monitoring of door status for industrial applications. It features a compact design with a sensing range of up to 1.5 inches, making it suitable for various door types. The switch offers versatility with multiple configurations, including end-to-end, side-by-side, and perpendicular mounting, allowing for flexible installation.

Installation

The Model 126 is designed for use with tungsten filament bulbs of 150-watt rating or

less at 120 volts.

1. Using the following guidelines, determine a suitable mounting location:

• The switch and actuator must be within the listed sense range. See Ordering/

Electrical Specifications.

• The actuator must be aligned with the switch—labels facing the same direction.

(See Figure 1.)

Important: When mounting in proximity to ferrous material (steel), the sense

range can be reduced 50% minimum depending on the shape and type of

material. Test the switch in specific applications to determine the actual

sense range.

2. Determine location of switch on door jamb. To ensure proper operation and that the

magnetic field not interfere with switching, do not locate closer than six inches

from hinge side of door.

3. Locate switch (B) and magnet (A) locations on door jamb and door. (See Figure 2.)

Drill a one-inch hole to accomodate these. (Do not hammer. This can damage the

switch.) Misalignment of up to 1/2-inch can be tolerated, but not in a ferrous metal

door. (To check if a door or jamb is ferrous hold a magnet to it. If it is attracted

it is ferrous.)

4. Connect the black line conductor, see Figure 3, to the fuse and fuse holder that are

provided. Connect the white neutral conductor to the load. Connect the flexible

conduit to a NEMA Type I enclosure, see Figure 2.C, using a properly sized and

acceptable 3/8 inch flexible conduit connector. If the switch is being used in a

branch circuit, connect to a UL listed relay with minimum rating of 120VAC/15A.

5. The switch and actuator must move in one of the approved directions.

See Figure 4.

Warning! To avoid switch failure determine the actual load of the switch circuit and

take steps to protect the switch from voltage spikes, current inrush and line/load

capacitance using the following recommendations.

• Surges from coils, motors, contactors, solenoids and tungsten filaments. Transient

protection, such as back-to-back zener diodes (Transorb) or an RC network, is

recommended for such loads to ensure that maximum ratings of the switch are

not exceeded.

• Line capacitance and load capacitance. An in-line resistor can be added in series

immediately before the load to limit the inrush current. The resistor can only be

added in series with the last wire just before the load. The voltage drop and the

power rating of the resistor must also be calculated as follows:

Voltage drop = I • R

Watts = I

• R

( I = maximum continuous current of the load)

To verify switch operation with an ohmmeter:

Set range at 20 mega ohms (switches with triac output, set ohm range at 20 kilo

ohms). For a normally open switch, the meter will read a high impedance with the

actuator away. It will read very high to infinity range (triac switches will read high kilo

ohm to infinity range) with the actuator within sense range. You will see the opposite

reading for a normally closed switch.

126-Y Actuator Only Included with all switches unless otherwise noted.

Warning— Each electrical rating is an individual maximum and cannot be exceeded!

Configuration with actuator away from the switch

Proximity of ferrous materials usually reduces sense range — typically by 50%. The shape and type of material cause a wide diversity of effects.

Testing is required to determine actual sense range for specific applications.

Can withstand inrush surge up to 4 Amps. Voltage Drop 1.5V. Minimum switch current 30mA.

Maximum 25 switches in series.

Barrel Switch Mounting Configurations

“T”

Three configurations are appropriate for recessed interlock applications. Moving the

actuator parallel to the switch can result in on/off/on signal if the actuator passes by

the switch rather than coming to rest in proximity to it. This is NOT a recommended

configuration for interlock/position applications. "T" configuration results

in non-actuation.
